I have a Django project and I want to add a background image to the HTML template. I have the following code:
<body class="standard-background-color standard-font-family" background="{% static '/images/background1.jpg' %}">
It displays the original size which is 5300 X 3100 or something like that. I want to change the image size for the background image but when I apply css to the body tag the images size is not changing. How can I change the image size to 1920 x 1080...
As Radiant Ahmed pointed out in his comment, if you want a background with opacity then it should be another div
With that in mind, you can use a pseudo element to create the background image container.
Also there is no need to resize the actual image in Photoshop to fit the screen (though it's kinda huge), use background-size: cover instead.
How background-size property works MDN
div {
width: 200px;
height: 200px;
background: red;
}
body::after {
content: '';
background: url('https://fillmurray.com/500/500');
background-size: cover;
opacity: 0.5;
position: absolute;
z-index: -1;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
<div>
<p>Yo! I'm the content!<p>
</div>
Correct me if I'm wrong, but I'm assuming that you are trying to set the size for the background image for html which is unaffected by the CSS for body.
In that case, just add !important after what briancaffey said so that it doesn't get overridden by other CSS:
html {
background-repeat: no-repeat !important;
background-attachment: fixed !important;
background-position: center !important;
-webkit-background-size: cover !important;
-moz-background-size: cover !important;
-o-background-size: cover !important;
background-size: cover !important;
}
It's not recommendable to set a background size of 1920x1080, because people have different viewport sizes, so it's more practical to adjust the size to their viewport using background-size: cover.
This seems to be a common question but the existing answers I see do not seem to work for me. I have a background image that is much taller than it is wide. I would like the height to be 100% of the height of body. So far I have tried:
body, html {
height: 100%;
min-height: 100%;
}
body {
background:url("NewLogo.png") no-repeat center center;
background-size: 100% auto;
}
I have also tried changing background-size: cover; but this also just makes the image large but cuts off the top and bottom.
Use contain. This will guarantee that the entire image appears in the container, and nothing is cut off:
body {
background:url("NewLogo.png") no-repeat center center;
background-size: contain;
}
Please note that if you want to have a background image which is cover and has got it's own height (without just being large, as wide as your browser but loosing the top & bottom as you said), you can try giving an appropriate height in vh to your background image.
body {
margin: 0;
}
#image {
background-image: url(https://images.unsplash.com/photo-1504387103978-e4ee71416c38?auto=format&fit=crop&w=2134&q=60&ixid=dW5zcGxhc2guY29tOzs7Ozs%3D);
background-repeat: no-repeat;
height: 293vh;
background-size: cover;
}
<div id="image">
</div>
Otherwise if you just want to make your background image cover, or if you want make it contain(though your image wouldn't fit the browser wide, it would be in it's real height), you can visit the following link:

I have an image that is my header. Here is my simple HTML:
<html>
<body>
<div class="wrapper" />
</body>
</html>
It fills the full width of the page, but I had to specify a height for it show up. Here is the css:
.wrapper {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
width: 100%;
height: 250px;
}
How do I make this image responsive? Right now when I expand the page it gets to the point where the pic is unrecognizable.
Didn't got your question quiet well, but I think you are missing a value here
background-size: 100%; /* 1 value is not wrong but you'll probably need 2 */
--^---
CSS
.wrapper {
background-image: url(http://images.google.co.in/intl/en_ALL/images/logos/images_logo_lg.gif);
background-repeat: no-repeat;
background-size: 100% 100%;
width: 100%;
height: 250px;
}
Demo
As ralph.m suggested, if you are using this image as your website background, than use the background property on body element instead of div
You need to use following CSS to make the background responsive
body {
background: url(bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

You need to think carefully about how you want/expect this to work. Without some actual content in the div, it will have zero height, which is why you needed to set a height on it; but in general, try to avoid setting heights. Presumably, if this is a "wrapper", it will be wrapping some content that will hold it open without you having to set a height.
As for the background image, you need to think about how it will behave. Do you just want it to appear in a strip along the top? If you use Mr Alien's solution, be aware that the image will stretch wider and wider and start to look odd. So we need some more information on what you are trying to do here.
Say, like in this example here: http://www.electrictoolbox.com/examples/wide-background-image.html
When I do it, I end up getting white borders around the image no matter what I do. What am I doing wrong?
If you're hoping to use background-image: url(...);, I don't think you can. However, if you want to play with layering, you can do something like this:
<img class="bg" src="..." />
And then some CSS:
.bg
{
width: 100%;
z-index: 0;
}
You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%; to apply to the whole page.
Here's a quick demo if you can't rely on background-size: http://jsfiddle.net/bB3Uc/
Background images, ideally, are always done with CSS. All other images are done with html. This will span the whole background of your site.
body {
background: url('../images/cat.ong');
background-size: cover;
background-position: center;
background-attachment: fixed;
}
You set the CSS to :
#elementID {
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) center no-repeat;
height: 200px;
}
It centers the image, but does not scale it.
FIDDLE
In newer browsers you can use the background-size property and do:
#elementID {
height: 200px;
width: 100%;
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) no-repeat;
background-size: 100% 100%;
}
FIDDLE
Other than that, a regular image is one way to do it, but then it's not really a background image.
the problem is the margin of body his default value is margin: 8px
and i make it margin : 0 so the image stretching and there is no white places
I have
body {
background: url(images/background.svg);
}
The desired effect is that this background image will have width equal to that of the page, height changing to maintain the proportion. e.g. if the original image happens to be 100*200 (any units) and the body is 600px wide, the background image should end up being 1200px high. The height should change automatically if the window is resized. Is this possible?
At the moment, Firefox looks like it's making the height fit and then adjusting the width. Is this perhaps because the height is the longest dimension and it's trying to avoid cropping? I want to crop vertically, then scroll: no horizontal repeat.
Also, Chrome is placing the image in the centre, no repeat, even when background-repeat:repeat is given explicitly, which is the default anyway.
There is a CSS3 property for this, namely background-size (compatibility check). While one can set length values, it's usually used with the special values contain and cover. In your specific case, you should use cover:
body {
background-image: url(images/background.svg);
background-size: cover; /* <------ */
background-repeat: no-repeat;
background-position: center center; /* optional, center the image */
}
Eggsplanation for contain and cover
Sorry for the bad pun, but I'm going to use the picture of the day by Biswarup Ganguly for demonstration. Lets say that this is your screen, and the gray area is outside of your visible screen. For demonstration, I'm going to assume a 16x9 ratio.
We want to use the aforementioned picture of the day as a background. However, we cropped the image to 4x3 for some reason. We could set the background-size property to some fixed length, but we will focus on contain and cover. Note that I also assume that we didn't mangle the width and/or height of body.
contain
contain
Scale the image, while preserving its intrinsic aspect ratio (if any), to the largest size such that both its width and its height can fit inside the background positioning area.
This makes sure that the background image is always completely contained in the background positioning area, however, there could be some empty space filled with your background-color in this case:
cover
cover
Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area.
This makes sure that the background image is covering everything. There will be no visible background-color, however depending on the screen's ratio a great part of your image could be cut off:
Demonstration with actual code
div > div {
background-image: url(http://i.stack.imgur.com/r5CAq.jpg);
background-repeat: no-repeat;
background-position: center center;
background-color: #ccc;
border: 1px solid;
width: 20em;
height: 10em;
}
div.contain {
background-size: contain;
}
div.cover {
background-size: cover;
}

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me
body {
overflow-y: hidden ! important;
overflow-x: hidden ! important;
background-color: #f8f8f8;
background-image: url('index.png');
/*background-size: cover;*/
background-size: contain;
background-repeat: no-repeat;
background-position: right;
}
Background image is not Set Perfect then his css is problem create so his css file change to below code
html {
background-image: url("example.png");
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
}
%; background-size: 100% 100%;"
I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:
http://css-tricks.com/how-to-resizeable-background-image/
http://css-tricks.com/perfect-full-page-background-image/
Read the descriptions for each of the articles and see if they're what you're looking for.
The first answers the following question:
Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.
The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "
Hope this helps.
Just add this one line:
.your-class {
height: 100vh;
}
vh is viewport height.
This will automatically scale to fit the device' browser window.
Check more here: Make div 100% height of browser window
body{
background-image: url(../url/imageName.jpg);
background-attachment: fixed;
background-size: auto 100%;
background-position: center;
}
Try this,
element.style {
background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}
I had the same issue, unable to resize the image when adjusting browser dimensions.
Bad Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
}
Good Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
background-size: contain;
}
The key here is the addition of this element -> background-size: contain;
Here's what worked for me:
background-size: auto 100%;
width: 100%;
height: 100vh;
background: url("../img/hero-bg.jpg") top center;
background-size: cover;
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
if you set min-height, for example:
min-height: 100vh;
You can use the below code to fit your background easily
body {
background: url(images/background.svg);
min-height: 100vh;
background-repeat: no-repeat;
background-size: cover;
}
Setting background size does not help, the following solution worked for me:
.class {
background-image: url(blablabla.jpg);
/* Add this */
height: auto;
}
It basically crops the image and makes it fit in, background-size: contain/cover still didn't make it fit.
